Overview

The acts_as_authentic method has a crypto_provider option. This allows you
to use any type of encryption you like. Just create a class with a class
level encrypt and matches? method. See example below.

Example

classMyAwesomeEncryptionMethoddefself.encrypt(*tokens)# the tokens passed will be an array of objects, what type of object is irrelevant,
# just do what you need to do with them and return a single encrypted string.
# for example, you will most likely join all of the objects into a single string and then encrypt that string
enddefself.matches?(crypted,*tokens)# return true if the crypted string matches the tokens.
# depending on your algorithm you might decrypt the string then compare it to the token, or you might
# encrypt the tokens and make sure it matches the crypted string, its up to you
endend
